People usually spend 1/3 of the day and night sleeping, i.e., they go to sleep at night and wake up during the day, forming a sleep-wake rhythm. Sleep-wake rhythm disorders are sleep disorders caused by a sleep-wake rhythm that is different from the usual one. The disorder is usually seen in adults, but is rarely seen in childhood or adolescence. Tests required for sleep-wake rhythm disorders: Based on the medical history and neurological examination, other necessary and selective auxiliary tests include: 1. 2.Blood routine, blood electrolytes, blood glucose, urea nitrogen. 3.Electrocardiogram, abdominal ultrasound, chest X-ray. 4.Sleep latency is normal or shortened, and the characteristic performance is sleep initiated by REM (SOREMPs). The more SOREMPs appear, the more it helps to diagnose episodic sleeping disease, and finding more than two SOREMPs can generally be diagnosed as episodic sleeping disease. However, the specificity of more than 1 SOREMPs for the diagnosis of the disease is not absolute. Cardiac arrhythmias, unplanned changes in work, chronic sleep deprivation, obstructive sleep apnea, and periodic leg movements during sleep can occur with 2 or more SOREMPs, which should be distinguished clinically.
